UNSPSC 31171711: Ring gears

UNSPSC 31171711 Ring gears, a Commodity code, encompasses the procurement of specialized industrial gearbox components and related pump and motor repair services by state and local water authorities, county facilities management, and special-purpose districts. Recent solicitations under this code show state and local buyers acquiring gearbox reducer units with taper bushings, electric motor rebuild services, and on-call maintenance contracts for pumping infrastructure. The West Basin Municipal Water District's RFP for on-call pump and motor repairs, rebuilds, and replacement services across recycled water facilities in Los Angeles County illustrates the operational scope: electric motors ranging from 1.5 to 800 horsepower, comprehensive rebuild services with performance testing and vibration analysis, and fixed-price contracting with cost-plus markup caps (10% for contractor parts, 5% for subcontractor costs). The Hillsborough County Board of County Commissioners' ITQ for two Dodge taper bushed reducer gearboxes and four taper bushing kits, procured for the Northwest Water Reclamation Facility in Tampa, Florida, shows the direct component purchasing within this code. Issuing bodies include municipal water districts, county commissions, and county departments managing water recycling and reclamation infrastructure, typically requiring vendors to maintain local repair capacity, hold five-plus years of specialized experience, and carry substantial commercial general liability and workers' compensation insurance.

Geographic activity centers on California and Florida. The West Basin Municipal Water District opportunity (Los Angeles County, RFP RFPTH0143, due October 1, 2026, $1,000,000 two-year not-to-exceed with one-year extension) and the Hillsborough County ITQ (Tampa, ITQ ITQ2600239, due May 8, 2026, $30,400 project estimate) represent the most recent activity. An unrelated DeKalb County tennis center IT infrastructure reconstruction (ITB 2026-076-ITB, due July 13, 2026) was tagged to this code but involves low-voltage cabling and conduit installation, not gearing or motor repair. Qualifying vendors must hold California Department of Industrial Relations Public Works Contractor Registration for municipal water district work, participate in pre-bid conferences where offered, and comply with E-Verify and tax-exempt procurement requirements. Set-asides target SBEs, LBEs, and VOBEs in West Basin procurement, with additional evaluation points or up to 10% price reductions available.
